Swiss police have arrested an elderly woman for spraying anti-war graffiti outside the headquarters of the Swiss National Bank. Her protest was in support of an initiative aiming to ban Swiss financing of any company that produces weapons.

Louise Schneider, 86, was put into a police vehicle on Tuesday morning after spray-painting the slogan “Money for weapons kills” on a billboard outside the Swiss National Bank's headquarters in Bern.

The phrase was painted on a temporary partition which is screening off a construction site at the bank as it undergoes renovations.Following the incident, the elderly peace activist could be seen smiling in photos while still holding her can of red spray paint.

Her action was in support of a political campaign launched by the pacifist Group for an Army-free Switzerland (GSsA), which aims to prevent banks from holding shares in companies that make weapons.
